Abstract:A strain of Amphimallon majalis (Razoumowsky) highly resistant to the chlorinated hydrocarbon cyclodiene insecticides was discovered in East Rochester, N. Y., during 1969. Doses producing 90-100% mortality of susceptible third-stage grubs produced 0% mortality of the resistant grubs. Eggs obtained from beetles collected from numerous areas of New York State were placed in chlordane-and dieldrin-treated soils. No kill of 1st-stage grubs occurred in collections from 3 sources in East Rochester. Moderate mortalities with both chlordane and dieldrin in the Syracuse collection and with dieldrin in the Newark, N. Y., collection may be indicative of resistance developing in these areas where dieldrin has been used extensively for European chafer control. Dieldrin was used in the Newark area at least twice as long as in the East Rochester area. Only diazinon and Dursban (0,0- diethyl 0- (3,5,6-trichloro-2-pyridyl) phosphorothioate) were effective in controlling grubs in field plots treated on July 2 and 9, 1969. Carbaryl was ineffective when applied July 2 but was effective when applied July 9, a week nearer hatching. The standard dieldrin treatment was completely ineffective in both applications. Timing applications of short-residual phosphate and carbamate insecticides to coincide with hatching appears essential for effective control of resistant European chafers.
